Also, When I pull the trigger multipul times it doubble clutches, or "burps" and that contributes to balls being chopped. Im going to take it apart tonight and give it a thouro cleaning. anyone else have problems like this? I mean I want to at least be able to shoot a 3 rd burst without it chopping balls, IMO thats just a ****ty marker if it cant do that
It's a 9.0?
Is it used? Has it just started to burp? or has it always done so?
"burps" or double fires are often due to a problem in the trigger/sear group. Check to make sure that none of the components are cracked or chipped. And make sure they can move smoothly (i.e. are clean and with a very light coat of oil).
It could also be damage on the rubber bumper that sits behind the bolt. Or the bumper could be missing.
As to the velocity of only 280 causing strange wingers, it sounds more like old dimpled paint as 280fps shouldn't cause any strange behavior in the paint.
Another possibility for chops when magazine fed
is double feeds due to the paint being too small for the detents. You can slightly bend the detents so they will better hold the small paint.
Chops via hopper feed I con't help you there, I refuse to run these great mag feed markers that way, so my assistance is just passing on of info I've heard from others.
